To all whom it may concern:

Be it known that I HENRY A. Wrsn' Wool), a citizen of the lini ed States, reading at New York, in the county of-- New- York and State of .Nev'v York, have invented a new and useful Pastinfi'Device for Web-Presses, of which the to owing is a specification.

This invention relates to a pasting device for use in connection with aweb press.

The principal objects of the invention arev to provlde a simplified and continuously opmargin of the web; to provide-a construc- 'tion'wh'ich crating means for applyingpaste along a can be operated without danger of scattering the paste, especiallywhen working at high'speed; also to provide simple and efiective applied in a uniform and safe manner and is slightly spread out in a uniform width on the web; means whereby the-paste can be forced on the web by pneumatic pressure;

means whereby the paste receptacle can readily be applied to the press and removed therefrom; and means whereby the operation of a plying the paste to the web will be Fig. 2 is an elevation of the paste conjtainer with parts in section;

Fig. 5 is a plan of a modified form of nozzle, and

Fig. 6 is a perspective view of a modified form of pasting device.

Ordinarily, web presses are provided with pasting devices in which a rotating disk is edge of this disk is immersed in a fountain-of paste and the other edge applies the paste to the web from a Is carried. A scraper; has to be emp o to keep its sides and edge clean so as to nish an even line of paste. This is a very means whereby the paste'is aste ed troublesome device because it odcupies a great deal of room an account of the disk,

and the fountain has to be located in between two webs. It also requires a rotating mecha'msm and is liable to throw the paste off the edge of the disk on account of the centrifugal force, especially when the press is speeded up beyond the ordinary speed.

difliculties and especially to permit of the running of the press at a high rate of speed without danger of throwing off any paste.

Referring first to the first four figures, it will be understood that although the details of the the device is intended for use on a web press and that this press constitutes the means for feeding the web referred to herein. On the 'frame of this press are shown a pair of ress are notillustrated herein, yet

transverse rods 10 for supporting the paste receptacle or container. 11. This container is carried on the rods by means of two circumferentially' adjustable carriers 12 which have ears 13 extending over these rods and supported thereon.

The container 11 is provided with flanges 14 to' which the carriers 12 are fixed in ad- ;li ukstedosition by means of screws 14 or the 1 e. with a bail 15 by which it may be carried and also lifted in and out of position on the rods 10. It is also provided with a cover 16 which is secured by a bayonet lock 17- in air-f tight condition on thetop of the container. Through which has a flange by which it is secured thereto. It is open at the bottom and is provided with a horizontal flat surface 19 at the top, parallel with the direction of the. web'W, and substantially in contact therewith. This surface is provided with a perforation 20, preferably substantially at the center thereof. This perforation is made small to permit of the paste being forced a small thread or stream, as will appear. From this perforation a shallow channel 21 extends to the ed e' of the surface 19, running in the same irection as the web and slanting upwardly toward the edge of this surface. This is provided for the purpose of smoothing out and thigning the strip of paste applied to the we In the form through to form shown in Fig. 5, a plurality his container is shown as provided the cover passes a paste tube 18 and th'eiv" 60 smooths itl'so as tb'get a-line of pests on the of l rforations 2c are shown. The-per ,tions 0120' constitute nozzles trusionof the paste. The container can be for the exfilled with paste un- 5 der ressure b applying a tube or nozzle to a filling nozzlg. 22, which will depress the of the valve 28 and the other the stem of go the valve 27 in the two extreme positions of the lever. For the purpose of operating this lever, so as to control the operation of the device upon thestarting and stopping of the e press, the startlng buttonping button 31 are provided in, addition to and the stopthem other connections, with circuits for energ1zing electro-magnets 32 and 33, re

energized by thepush 80' 31, the lever. 28 is shown in Fig. 1 and ng of the stop button oved to the position the exhaust valve 27 V spectively. When electro-magnet 33 is .is. depressed and obned. Atthis timethe inlet valve is al owed to close by. its spring. .When the.

starting button is $5 pushed, the'opposite condition takes pla'ce.

A s ring pawl 35 is shown for yieldmgly hol ing the'lever in either extreme position.

The operation' of the device. is

e container is; simply dropped into posi- 40 tion on the rods 10 and connected up'in the thejsta'rtingbutton, the valve 2 is opened I a ve 28 closed so that air pressure is admitted to the pastereceptacle. At this time, of course, the press starts and the paste is forced through 0 enin fagamst-the surface of the web as t e latter travels. The passage of the paste along the channel 21 spreads it and Web, of u'iii-form width and thic ess. The

pressin ofthe stop button willrelieve the. inte rior ofthe cgri t siner of the air pressure and'stop' the flow of paste immediately. 66 Thusthe paste will not be blown'out when no web is running,'as in case of ampaper break, or when theweb is being threaded p in the press.

' This apparatus'requires very littleroom,

as it can be made to fit the availablespace.

It is inexpensive because it has no movin parts. I It will work efficiently, regardless 0 speed because of the eliminatlon-of the element of centrifugal force.

he pipe sections 41 immediately above I: these couplings are provided with ball checks 45 to prevent leakage of paste'when thecans areremoved. These cans are connected with the air pipe line 46' by sections of hose 47 or the like, detachably connected withthe cans; The cans are shown as supported on 48 and the tubev 40 asbeing. carried by a suitable brace 49 0 1,-. the frame of the press.

The especial advantage of this construc-v out having tostopthe press if one of the cans has to be removed. When this is done,

the. stop cock 50 connected to that can is shut, that hose 47 disconnected from the can, and the coupling the other can.

' Although Ih'ave illustrated and described of theinvention, I am aware' of' the "fact that miniy'modifica tions. can be made therein by any person tion is the simplicity and the means where- 44 on that side opened. The check valve immediately closes this-connection and the paste continues to flow from skilled in the art without departing from the scope of the invention as expressed in the cla1ms.
